Central pressure augmentation is associated with greater backward wave amplitude and shorter transit time and is higher in women for reasons only partially elucidated. Augmentation also is affected by left ventricular function and shapes of the forward and backward waves. The goal of this study was to examine the relative contributions of forward and backward wave morphology to central pressure...

Shear-wave splitting (SWS) analyses are essential in understanding the structure and dynamics of the Earth’s deep interior. While splitting measurements have excellent horizontal resolution relative to other anisotropy-measuring techniques, their vertical resolution is low due to the steep incidence angle of the seismic phases used by the analyses. Here, using synthetic and real data, we presen...

The prevalence of leprosy varies between continents. Likewise, countries within a continent have differing rates of prevalence of leprosy (15). Even countries in which leprosy is endemic may demonstrate variations in leprosy prevalence from one state to another, and even from one district to another within the same state (13 . 14 ._ 15). The reasons for these variations have not been fully expl...

The astrophysical factor for the proton weak capture on 3 He is calculated with correlated-hyperspherical-harmonics bound and continuum wave functions corresponding to a realistic Hamiltonian consisting of the Argonne v 18 two-nucleon and Urbana-IX three-nucleon interactions. The nuclear weak charge and current operators have vector and axial-vector components, that include one-and many-body te...

A trial wave function for two-dimensional quantum-dot helium in an arbitrary perpendicular magnetic field a system of two interacting electrons in a two-dimensional parabolic confinement potential is introduced. A key ingredient of this trial wave function is a Jastrow pair correlation factor that has a displaced Gaussian form. The above choice of the pair correlation factor is instrumental in ...

The analytical solutions of wave induced horizontal and vertical forces on perforated caissons resting on porous elastic seabed have been established. The solution in the seabed is divided into a symmetric part and an anti-symmetric part. A numerical experiment has been carried out to examine the effects on horizontal forces, vertical forces and phase lags between them due to the relative wave ...
